What is the best way to plant a tree?

Be sure to call the national 811 hotline to have underground utilities located before you dig.  Then, dig 2-5x wider than the diameter of the root ball.  It’s best to dig with sloping sides to allow for root growth.  The trunk flare should actually sit slightly above the ground with the top most roots buried 1-2 inches below.  Be sure to fill in with native soil unless there’s too much clay. Use soil to gently fill air spaces.  If using mulch, allow 1-2 inches between the mulch and the trunk.
